CHAIR CONSTRUCTION Application filed March 10, 1928.

The present invention relates to improvements in furniture and hasreference more particularly to a chair construction.

One of the important objects of the present invention is to provide achair that can be readily and easily assembled or disassembled, meansbeing provided for positively securing the parts of the chair inassembled relation without necessitating the gluing of the partstogether, such as is commonly done in the assembly of chairs now on themarket.

Another important object of the invention is to provide a chairconstruction whereby should any part of the chair become broken the samecan be readily and easily removed and replaced with a new one, withoutnecessitating the loss of any considerable length of time or labor,thereby obviating the necessity of having to entirely discard the chair.

A still further object is to provide a chair construction of the abovementioned character, which is simple, inexpensive, strong and durable,and further well adapted for the purposes for which it is designed.

Other objects and advantages of the invention will become apparent asthe nature of the invention proceeds and when taken in connection withthe accompanying drawing.

In the accompanying drawings, forming a part of this application and inwhich like numerals designate like parts throughout the several views;

Figure 1 is an enlarged view, partly in elevation and partly in sectionof a chair construction embodying my invention.

Figure 2 is a fragmentary top plan view, partly shown in section to moreclearly illustrate the connecting means between adjacent members of thechair.

Figure 3 is a group perspective view of one of the front leg members,and the adjacent side rail and the fastening means therefor.

Figure 4 is a sectional view, taken approximately on the line 4-4 ofFigure 2, looking in the direction of the arrows, and

Figure 5 is a fragmentary sectional view of a modification of theadjacent ends of the hand rail, or rest, and the support for the forwardend thereof. v In the drawings, wherein for the purpose Serial No.260,624.

of illustration is shown the preferred embodiment of my invention, thenumeral 1 designates generally my improved chair con struction, the samecomprising the front and rear legs 2 and 3 respectively, the back 4 of 5the chair, including extensions formed on the upper ends of the rearlegs. A back rest 5 extends between the upper ends of the extensions 4and suitable wooden screws 6 are driven through the sides of the upperends of the extensions into the respective ends of the backrest asclearly shown in Figure 2, the socket provided in the outer face of eachextension to accommodate the head of the wooden screw being closed bymeans of a plug 7 Suitable slats 8 extend vertically in spaced relationwith respect to each other between the back rest 5 and the cross piece9. At their upper end portions, the legs 3 are provided with recesses Ain the inner walls of which are the horizontal shoulders B.

The seat portion of the chair is shown at 10 and the same rests on theseat supporting frame 11, that is secured between the front and rearlegs in the manner to be presently described. The forward end portion ofeach side rail 12 of the seat supporting frame 11 is formed with alongitudinally extending bore 13 that extends from the forward end ofthe side rail, rearwardly for a considerable 30 distance. The bottomface of this particular side rail is formed with a nut receiving socket14 that extends upwardly and beyond the bore 13, and which bore isintercepted by the socket.

A nut 15 is disposed within the socket 14 in such a manner as to havethe threaded bore of the nutin registration with the bore 13, and a bolt16 extends transversely through the upper end of each front leg, themajor portion of the bolt projecting beyond the rear face of the frontleg and as is clearly shown in Figure 1, the free end of the boltextends into the bore 13 and the threaded end 17 of this bolt willengage with the threaded bore of the nut 15, and by actuating the kerfedhead 17 with a screw driver or the like, the front legs will be securelyheld in position against the forward ends of the side rails of the seatsupporting frame 11.

til

The front side of each front leg member is formed with an enlargedsocket to accommodate the headed end 18 of the bolt and this socket willbe closed by a removable plug 19 after the parts have been properlyassembled together.

The upper end of each front leg member is formed with a tenon 2 thatfits within a suitable socket C provided therefor in the bottom face of.the seat portion 10, as also clearly shown in Figure 1. The rear legs 8are connected to the rear ends of the side rails 12 which are mounted inthe recesses A by wood screws 20 and the rear portion of the seat 10extends beyond the rails 12 into the recesses A and rests on theshoulders B and is secured to the rear leg members by a bolt and nutarrangement similar to that by which the front legs are connected to theforward ends of the side rails and this arrangement is shown generallyat 21, in Figure 1. As seen in Figure 1 of the drawings, the uppersurfaces of the rails 12 are in the horizontal planes of the shouldersB.

Extending between the respective pairs of the front and rear legs arethe rails 22, the ends of the rails being formed with longitudinallyextending bores .48 and the intercepting nut receiving sockets 24, thatextend upwardly from the bottom face of the rail to accommodate thethreaded bolts 25, whereby these side rails 22 are rigidly secured tothe front and rear leg members.

Cross rails 26 extend between the side rails 22 and are connectedthereto in a similar manner.

Extending upwardly from the outer sides of the rails 12 and seat 10 arethe curved posts 27, that are securely connected at their upper ends tothe forward ends of the arm rails or rests 28, the rear ends of said armrests or rails being operatively connected to the respective extensionsassociated with the rear legs 3 and the same connection is providedbetween the ends of each arm rest or rail and the respective posts andextensions as is provided for securing the upper ends of the front legmembers to the forward ends of the side rails 12 and in addition, saidelements are provided with cooperating tongues and sockets as generallyshown at 29, in Figures 1 and 2. The posts 27 are detachably secured tothe rails 12 and seat 10 by the removable securing elements D and E,respectively, which also constitute means for maintaining the forwardportion of the seat 10 in position on the frame 11 and the front legs 2.

In Figure 5, the modification is shown wherein the upper end of eachpost 2? is formed with a cut out portion 30 and the forward ends of theadjacent arm rests is pro vided with a shoulder 31, for co peration withthe cut out portion 80 and furthermore a bolt and nut connection isprovided between these adjacent parts, whereby the same can be readilysecured together.

It is to be understood, of course, that wherever a socket is formed inone of the parts of the chair, to accommodate the kerfed head of thesecuring bolt or a wooden screw, that such socket is closed by aremovable plug, shown at 19.

A chair construction of the abovementioned character will permit theparts constituting the chair to be readily assembled or disassembled,and should any one of the parts become broken, the same can be readilyreplaced with a new one, without necessitating the entire rebuilding ofthe chair, thus saving considerable expense. Also, by removing the plugs19, the belts or wood screws can be readily and easily tightened shouldany looseness occur as a result of the use of the chair.

A chair constructed in the manner as above described will at all timesbe strong and durable.

lVhile I have shown the preferred embodiment of my invention, it is tobe understood that minor changes in the size, shape, and arran 'ement ofparts may be resorted to, without departing from the spirit of the invention and the scope of the appended claim.

Having thus described ni invention, what I claim as new is:

As a new article of manufacture, a chair including front and rear legs,said rear legs being recessed at their upper end portions, horizontalshoulders in the recesses, a supporting frame supported, at its rearend, in the recesses and having its upper face in the horizontal planeof the shoulders therein, means for detachably securing the frametherein, said frame having its forward end in abutting engagement withthe side of the front legs adjacent the upper ends thereof anddetachably secured thereto, tenons on the upper ends of the front legs,a seat mounted on the frame and extending into the recesses in the rearlegs and mounted on the shoulders therein, means for detachably securingthe seat therein, said seat extending over the upper ends of the frontlegs and being provided, adjacent its front ends, with sockets in itsbottom face for the reception of the tenons, a back rest extendingupwardly from the rear legs, vertical posts on the outer sides of theframe and the seat and extending upwardly therefrom, securing elementsextending transversely through the lower end portions of the posts andinto said. frame and seat and constituting means for detachablysupporting the posts thereon and for detachably maintaining the forwardportion of the seat on the frame and the front legs, and arm restsextending between the upper ends of the posts and the back rest.

In testimony whereof I atlix my signature.
